OPTIMIZEIMAGEDIRCALLBACK

Summary

Gives the user information about the image(s) being optimized by L_OptOptimizeDir.

Syntax

#include "l_bitmap.h"

L_INT pEXT_CALLBACK YourFunction (pOptImgDirCBInfo, pUserData)

Parameters

pOPTIMIZEIMAGEDIRINFO pOptImgDirCBInfo

Pointer to an OPTIMIZEIMAGEDIRINFO structure that contains information about the image(s) being optimized, such as the completion percentage for the current image being optimized, and the completion percentage for all files being optimized.

L_VOID * pUserData

A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the L_OptOptimizeDir function. (This is the same pointer that you pass in the pUserData parameter of L_OptOptimizeDir function.)

Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns

Value	Meaning
SUCCESS	The function was successful.
ERROR_OPT_SKIPIMAGE	Skip the current image and optimize the next image.
Any other value	An error occurred. Stop the whole optimization operation. Refer to Return Codes.
